The leaders of the US, South Korea and Japan last month met at Camp David for their first trilateral summit. The resulting agreement to deepen military and intelligence cooperation has steered Northeast Asian geopolitics into uncharted territory.
In view of the rising threat from North Korea, deteriorating ties with China and Russia’s invasion of Ukraine, US President Joe Biden’s administration has pursued a bold and systematic regional strategy. Multilateral coalitions like this one, the reinvigorated Quad (Australia, India, Japan and the US) and the relatively new AUKUS arrangement (comprising Australia, the UK and the US) augment the traditional hub-and-spoke model of security cooperation in the Asia-Pacific region, with the US at the center of each.
From the US perspective, the strained relationship between South Korea and Japan — the most important allies of the US in East Asia — has long been a strategic obstacle. Since he was former US president Barack Obama’s vice president, Biden has been eager to help the two nations — long at odds over historical disputes and territorial issues — mend fences.

South Korean President Yoon Suk-yeol’s audacious decision early in his presidency to normalize relations with Japan offered Biden a rare opportunity. Specifically, Yoon decided in March not to seek money from Japan to compensate South Korean victims of forced labor during World War II — a proposal that, at the time, only 35 percent of South Koreans supported and about 59 percent opposed.
Forging closer ties with Japan is crucial for Yoon to achieve his foreign-policy goal of making South Korea a pivotal global player. Former South Korean president Park Geun-hye, for example, struggled to pursue her ambitious Northeast Asia Peace and Cooperation Initiative while maintaining a hostile relationship with such a large and important neighbor. Whether Yoon can smooth over the differences and cement more positive bilateral ties remains to be seen.
China and North Korea are likely to push back against the effort to institutionalize cooperation between the US, South Korea and Japan, but to reach its full potential, this new deterrence structure must be accompanied by an openness to dialogue with both nations.
To guard against misunderstandings and prevent further escalation of the situation in the Taiwan Strait, which is China’s central concern, the US must step up its efforts to re-establish military communication channels with China. Likewise, South Korea and the US, supported by Japan, should communicate to North Korea that they are ready and willing to engage in diplomatic dialogue — the enhanced trilateral deterrence posture envisioned at Camp David will not achieve regional peace on its own.
However, the most formidable challenge to the partnership is domestic political pressure, especially in South Korea. Critics of Yoon’s decision to thaw relations with Japan believe that the president is naive and that South Korea is paying dearly for joining this group while getting very little in return. For Yoon, convincing these naysayers will be critical to the success of his presidency — his margin of victory in the presidential election was just 0.74 percent and, after almost 16 months in office, his approval rating stands at only 37.6 percent.
There are three ways that the US and Japan could help South Korea solve this challenge. First, while strengthened security cooperation is certainly an important foreign-policy achievement, the group must accelerate the implementation of their agreements on economic and technological assistance. Making visible progress on these fronts and delivering tangible benefits to Yoon’s critics could help shift public opinion toward a more favorable view of the new partnership.
Second, if China continues to engage in coercive commercial diplomacy against South Korea, the US response would matter a great deal to South Koreans. Former US president Donald Trump’s administration did nothing when China sanctioned South Korea for its deployment of a US Terminal High-Altitude Area Defense system in 2016. Whether the three nations can act together on this issue would be a key factor in deciding the group’s future. Moreover, the Biden administration could also turn South Korean public opinion against the security agreement if it enacts more legislation that discriminates against foreign companies, as both the Inflation Reduction Act and the CHIPS and Science Act do.
Third, Japanese Prime Minister Fumio Kishida must be proactive in improving ties with South Korea. While Kishida has been cooperative, many believe that his actions are not commensurate with the political risks taken by Yoon. They also fear that inappropriate, and often crude, comments about Japan’s long occupation of Korea made by some members of Kishida’s Liberal Democratic Party could undermine Yoon’s attempt to extend an olive branch.
The challenge of winning over public opinion in South Korea pales in comparison to the risks for the region if Trump wins the US presidential election next year. In that case, the infant partnership might have no future. To solidify his diplomatic achievements and to prevent a policy reversal in Northeast Asia, Biden must fully implement every aspect of the agreements reached at Camp David before November next year.

We are used to hearing that whenever something happens, it means Taiwan is about to fall to China. Chinese President Xi Jinping (習近平) cannot change the color of his socks without China experts claiming it means an invasion is imminent. So, it is no surprise that what happened in Venezuela over the weekend triggered the knee-jerk reaction of saying that Taiwan is next. That is not an opinion on whether US President Donald Trump was right to remove Venezuelan President Nicolas Maduro the way he did or if it is good for Venezuela and the world. There are other, more qualified
This should be the year in which the democracies, especially those in East Asia, lose their fear of the Chinese Communist Party’s (CCP) “one China principle” plus its nuclear “Cognitive Warfare” coercion strategies, all designed to achieve hegemony without fighting. For 2025, stoking regional and global fear was a major goal for the CCP and its People’s Liberation Army (PLA), following on Mao Zedong’s (毛澤東) Little Red Book admonition, “We must be ruthless to our enemies; we must overpower and annihilate them.” But on Dec. 17, 2025, the Trump Administration demonstrated direct defiance of CCP terror with its record US$11.1 billion arms
The immediate response in Taiwan to the extraction of Venezuelan President Nicolas Maduro by the US over the weekend was to say that it was an example of violence by a major power against a smaller nation and that, as such, it gave Chinese President Xi Jinping (習近平) carte blanche to invade Taiwan. That assessment is vastly oversimplistic and, on more sober reflection, likely incorrect. Generally speaking, there are three basic interpretations from commentators in Taiwan. The first is that the US is no longer interested in what is happening beyond its own backyard, and no longer preoccupied with regions in other
As technological change sweeps across the world, the focus of education has undergone an inevitable shift toward artificial intelligence (AI) and digital learning. However, the HundrED Global Collection 2026 report has a message that Taiwanese society and education policymakers would do well to reflect on. In the age of AI, the scarcest resource in education is not advanced computing power, but people; and the most urgent global educational crisis is not technological backwardness, but teacher well-being and retention. Covering 52 countries, the report from HundrED, a Finnish nonprofit that reviews and compiles innovative solutions in education from around the world, highlights a
